Specification of Letters Patent.

Patented June 9, 1908.

Application filed August 24, 1907. Serial No. 390.019.

To all whom it may concern: Be it known that I, JAMEs E. MCINTIRE, acitizen of the United States .'residing at C- lumbus, in the county ofFranklin and'State of Ohio, have invented certain new and usefulImprovements in Acetylene-Gas Genera tors, of which the following is aspecification. My invention relates to acetylene gas generators and hasfor its object the provision of a device of this character constructedin such manner that the gas generated must pass through the water thatis brought into contact with the calcium carbid, before the whereby thegas will be washed and cleansed of all impurities before being permittedto pass to the burner. Further objects and'advantages of the inventionwill be set forth in-the detailed description which now follows. I

In the accompanying drawing: Figure 1.

erator constructed in accordance with the inventlon, and, F 1g. 2 1s aplan view of said Like numerals designate corresponding parts in both ofthe figures of the drawing. Referring to the drawing, the numeral 5designates a water supply tank which is provided with a cap plate 6 anda bottom plate 7. 8 designates a generating tank which is plate 10.Threaded into this cap plate 10 is a pipe 11 which leads to a calciumcarbid re ceptacle, not shown. A valve 12 which is preferably a gatevalve in order that it may be opened to a considerable extent, isprovided to control the passage of the calcium carbid to the tank 8. Apipe 13 leads from the generating tank 8 to a safety valve cesing 14 anda valve 15 controls the-passage of gas through this pipe. A safety valve16 of any desired construction is mounted within the casing 14 and a gasconducting pipe 17 leads from the safety valve casing to a nipple 18.Mounted upon' this nipple is apressure gage 19 adapted to indicate thepressure of the gas generated, as will be-hereinafter'described. A pipe20 leads from the nipple 18 to the lower portion of the water tank 5. Asecond pipe 21 leads from the upper portion of the water tank 5 to thetw nip le 22. A short pi e 23 connects thls n1 p e-with valve 24 an aservice pipe s from this valve to a point at which I the gas is to beused. A pipe 26 leads from the tank 5 into the tank 8 and is closed by anipple 27 at one end. with a series of perforations 2S and a valve 29 islocated in this pipe. A pipe 30 leads from the lower portion of the tank5 and has,

a valve 31 located therein. A pipe 32 leads from the lower portion ofthe casing S and has a valve 33 located therein.

The operation of the device is as follows: The valve 12 when open,permits the carbid indicated at 34 -to fall through the pipe 11 and intothe tank 8. When the valve 29 .is opened, water passes through the pipe26 from the tank 5 and falls from the perforations 28 upon the carbid,thereby generating gas in the usual and well known manner. This gaspasses through pipes 13, 17 and 20 to the lower portion of the watertank 5 and ascends through the water, being thereby thoroughly washedand cleansed of allimpurities. This gas collects in the upper portion ofthe tank 5 and is conducted from there by the pipes 21 and 25. Thepressure gage 19. provides means for determining the pressure within thetank 5 at alltimes, while the safety valve 16 will relieve the pressurewith in the apparatus if it should at any timego beyond a predeterminedpoint. The pipe '32 This pipe is provided.

and valve 33 provide means for removing the ash of the calcium carb'idfrom the tank 8. It is but necessary to open the valve. 33 in order toaccomplish this. The pipe 30 which leads from thelower portion of thetank 5, provides means for blowing off this tank and thereby removingany sediment which may have collected in thegtank. The casing of thevalve 12 is provided with a valved nipple 35 to which water may beconducted through a hose or like conducting member. Vhcn the valve ofthis nipple is open and the valves 15 and 29 are closed and the valve 33opened,

the flow of water will be straight through the generating tank 8 andwill flush all of the cal cium carbid ash from this generating tank.

If the valves 12 and 29 are closed and the valve 15 be opened,.the tank5 may be filledthrough the pipes 13, 17 and 20.

From the foregoing description, it will be seen that simple andefficient -.n1eans are herein provided for accomplishing the objects ofthe invention and while the elements shown and described are welladapted to serve the purposes for. which they are intended, it is to beunderstood that the invention is not limited-to the precise constructionset forth, but includes Within its urview such changes as may be madewit '11 the sec e of the appended claims.

hat I claim, is:

In a device of the character described; the combination with a Watersupply tank, a generating tank, a gas su ply pipe leading from thegenerating tank through thetop of the water supply tank and terminatingnear the bottom of said Water supply tank, a service pipe extendingdownwardly through the water supply tank and leaving said water supplytan at the lower portion thereof, said service pipe opening into. thewater su ply tanknear the top thereof, a pipe leading Tom the watersupply tank into the generating tank, a valve ocated within said lastnamed pipe, a pi e leading into the top of the ener- 4 atlng tan andadapted to conduct ca cium carbidto said tank, a valve located withinsaid pipe, and a second valve adapted to con- .duct water under pressureto the casing of JAMES E. MOINTIRE.
